Topic: 334 Subscriber set causes busy signal (Read 2001 times)

I have my nicely re-painted and refinished finished 334 with freshly nickeled bells and my rusted beaten up 334 and of course the rusted boat anchor rings louder than any of my other phones and the clean pretty one causes a busy signal. Here's how it is wired as far as I can tell:

Sorry, I meant the white ringer wire on the working 334 that I used as a model is hooked up to GN. Judging from the layers of crud it has been that way for some time. The condenser and coil wires are harnessed together and have not been rearranged as far as I can tell. I have not hooked up a phone to it yet to see what happens.

The way you describe it was how the problem 334 had been set up, and did not work. I think the real problem with the non-working 334 was the integrity of the wiring itself, I had a couple wires break off as I was moving them around. I rigged them up so they conduct current, returned to the original configuration and it works. The other 334 configuration was a red herring.

White? WE ringer wires are usually red and black and the condenser (capacitor) wires for the ringer are usually slate and yellow. Maybe the wires have become discolored with age, and you are seeing one of the condenser wires. Sometimes the colors get so faded, they can be next to impossible to discern.

If it used to be red it's white now, and it goes directly from the ringer to GN. Also, it rings really loud. I set it aside for now to concentrate on preparing phones for the sale I am in .this weekend

Looking at the diagram on the cover of a 534A, which should be similar: if it is correctly wired and all components are good, then the only difference in connecting a ringer to L1 and GN rather than L1 and C is that you now have added the secondary of the induction coil in series with the ringer. This is only 9 ohms so it should ring either way. Not sure what will happen when you try to connect a phone to it.

What is the induction coil in your set? No. 46 or earlier, No. 20, 29?

It does no look like a #46. There are no markings. 16 ohms between 1 & 2 and 27 between 3 & 4 would make it a No. 20 I believe.

However, I don't know why yours does not work with the ringer on C.

That 334A works fine now with the white/red wire attached to C:
